We got a new pool & I switched over to a salt system. The buddy who is plumbing it still hasn't got it done! It's been sitting with salt in the water , water level up to eyeball, for 2 weeks and is starting to get green. I'm very frustrated with him to say the least. Can I put salt water oxidizing shock in it without it circulating?I can stir it up with brush & net. It is potassium monopersulfate as active ingredient. Gosh, if I'd have just stuck with chlorine I'd know what to do. Thanks for yor help.
